"Then tap Volume Up > Volume Down > Power > Volume Down and the phone flashes the OS version stored in memory (same as Factory Reset)."
I see the Exclaim screen. However, when I tap Vup, Vdown, power, vdown my phone start as normal. What is my problem? (my phone 920, Winphone 10 TP)

I'm not sure, unless you are pushing the Power button too long or too hard. It is a very quick and light Tap. Win 10 TP may have something to do with it... I'm not testing Win 10 Mo right now so I can't say. I never tried a button press Hard Reset on 10.
